Electronics Parts / PCB / PCBA Quality Control Process

Incoming Quality Control (IQC)

• Inspection of raw materials and components upon arrival to ensure compliance with specifications.

In-Process Quality Control (IPQC)

• Continuous process monitoring to ensure product quality at every stage.

• Process control audits conducted station-to-station to assess product performance during manufacturing.

Testing and Inspection

• 100% Electrical Testing & AOI (Automated Optical Inspection) Testing

• 100% Hole Inspection to verify drill accuracy and plating integrity.

• 100% Final Inspection before shipment.

Final Quality Audit

• Conducted using the C=0 Sampling Plan, AQL 0.65 to ensure defect-free products.

Advanced Inspection & Testing Methods

• Visual Inspection: General quality check.

• X-ray Inspection: Essential for BGAs, QFNs, and bare PCBs to detect hidden defects.

• AOI Testing: Used for detecting solder paste quality, 0201 component placement, missing components, and polarity issues.

Strict Compliance with International Standards

With years of experience in PCBA production and foreign trade, we have established a complete inspection system and advanced testing equipment. All PCBA products strictly adhere to IPC-A-610 international electronic industry inspection standards, PCB bare board manufacturing and acceptance follow IPC-A-610 Class II & Class III standards, ensuring compliance with high international quality requirements.
